What is the mind? It seems to be directed and controlled by our actual physical brains.
If a person is in a coma from brain injury they can not be aware of themselves or their surroundings.
The mind seems to go in the direction the brain tells it to, being in a coma seems to mean both the incapacitation of the brain and mind.
This makes people very upset, if the brain is the mind, then the mind is finite, it is physical, it is capable of dying, it is capable of non existence.
This bothers people who are religious, who are spiritual and those that believe in any God or gods or supernatural eternal life after death.
If the mind is the brain, and I think it is, then there is no continuation of the mind outside of the physical body after death, therefore their is no ongoing consciousness, no soul or spirit after death, no continuing incorporeal self after death.
This terrifies religious people and theists, it is clearly true there is no mind, soul or spirit after death.
And this fact completely makes the concept of any God or gods existing and loving us personally totally irrational.
But, believing in God or the gods is always irrational, there is no evidence for such nonsense, no physical proof of God, gods, spirits, souls, or eternal life.
These things are fantasies that adults use to try to comfort a child when a relative or friend dies, which is understandable, maybe for young children the concept of God, even if is not real, is needed when death occurs and has to be explained to a five year old.
But you and I are not five year old children, we are men and women, we do not believe in Santa Claus or the Easter Bunny anymore, those fantasies have outlived there usefulness in adult hood, they are not needed.
When an adult clings to an absurd fantasy like believing in God or the gods, it is simply a childish way for an adult afraid oblivion and nonexistence after death, they are afraid of reality, so they construct fantasy to hide reality.
They are wasting their lives hoping for a next life with God or gods that do not exist.
Rather than living fully and joyfully in this life, they become paralyzed by fear of getting to a non existent after life.
